Specification of Letters Patent.

Patented Jan. 5, 12th.

Application filed June 22, 1914;. Serial No. M64379.

To all whom it may concern:

Be it known that I, CHARLES S:I'A RKS, a citizen of the United States,residing at Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented certain new vand useful Improvements in\Vrenches, of which the following is a specification.

This invention relates to new and useful improvements in wrenches, andhas for its principal object to provide a ratchet wrench which isadiustable automatically to permit the same to be used on nuts ofdiflerent sizes.

Another object of the invention is to provide a wrench in which the headis permitted to rotate in one direction and which may be applied to nutsfrom either side so that the nut may be tightened or loosened asdesired.

A further object of the invention is to provide a novel means forholding the ratchet spring in place to prevent the same from becominginoperative andpermlt a new spring to be inserted should the old springbecome worn or otherwise unfit for use.

With these and other objects in view, the invention consists in thenovel combination and arrangement of parts which will be fully set forthin the following specification and accompanying drawings, in which,

Figure 1 is a side view in elevation of a. wrench constructed inaccordance with this invention, Fig. 2 is an edge view of Fig. 1 showingportions broken away to more clearly illustrate the details ofconstruction I and also showing the same as it would appear with a boltin place, Fig. 3 is a view in elevation of the portion carrying thespring and showing the ratchet wheel in position, Fig. 4 is a transversesectional view taken on line 4-l of Fig. 3, Fig. 5 is a longitudinalsectional view taken on line 55 of Fig. 1, and Fig. 6 is a view inelevation of the inner side of the cooperating elements.

Referring now to the drawings by characters of reference, the numeral 1designates one of the wheel holding elements, while the numeral 2designates the cooperating element. These elements 1 and 2 are heldtogether by means of the lag screws 3 in such a way as to form a handlefor the wrench. A suitable enlargement 4 is formed at one end of each ofthe elements 1 and 2 and these enlargements are provided with theenlarged central apertures 5 forming the rings 6, the use of which will.appear upon referring to Fig. 2. These rings 6 are formed of the recesed portions 7 in which recesses the ratchet element of the wrench arefree to turn.

The rotatable element hereinbefore referred to, is designated generallyby the numeral 8 and comprises the body portion 9 having the peripheralflange 10 formed thereon. This peripheral flange is provided with aplurality of peripheral teeth 11 which are arranged to engage the springas will be more fully hereinafter described. The body portion 9 isrotatably mounted in the rings 6 as clearly illustrated in Fig. 2 and isprovided with the central rectangular aperture 12 having the adjustablenut receiving members which will be more fully hereinafter described.

Secured within the recess 13 formed in the element 2 are provided theblocks 14: and 15 between which the leaf spring 16 is held. These blocksare made to fit tightly so that the spring is held against movement, andare secured in place by means of the U-bolts 17,'the free arms of whichextend through the blocks and through the element 2 and are providedwith the nuts 18 which lie in the countersunk portion 19 as clearlyshown in Fig. 4. It will thus be seen that the spring is removably heldand may be easily and quickly removed and a new spring replaced shouldthe same become inoperative for any reason.

The jaw member, which is arranged to fit the rectangular aperture 12, isformed of a plurality of rectangular members 21 and 22 which are ofgraduated sizes so that the element 21 is slidable in the element 20 andthe element 22 is slidable-in the element 21. Secured to and extendingthrough the rectangular element 20 is a suitable pin 23 which isarranged to extend into the slot 24 formed in the element 21 and saidelement 21 is provided on the side opposite the slot with a pin 25,which is arranged to slide in the slot 26 formed in the element 21. Thusit will be seen that the several elements may be free to move withrelation to each other, but still will be held in such a way as to limitthe movement and prevent any parts from becoming lost.

It will be apparent from the foregoing that in use the wrench is appliedto a nut in the manner illustrated in Figs. 2 and 5. As shown in Fig. 5,the element 20 is of the proper size to fit the head of the nut teethofthe rotatableand will ush the inoperative members outwardly. t will thusbe seen that a wrench which is capable of use for. difierent' size nutsand which is arranged to turn the nuts in opposite directions, isprovided and the construction thereof is so that the same isautomatically adjustable, thereby eliminating any inconvenience.

\Vhile in the foregoing there has been shown and described the preferredembodiment of this invention, it is to be understood that such changesmay be made in the combination and arrangement of parts as will fallwithin the spirit and scope of the invention as defined in the appendedclaim.

Having thus described my invention, I claim:

A wrench including a pair of cooperating members forming handle ortions,each of said members being provi ed with enlargements at one end, saidenlargements being recessed and provided with enlarged centralapertures, a rotatable element mounted to rotate in the apertures, saidrotatable element being provided with a toothed peripheral flange a pairof blocks carried in one o the recesses in the elements formin thehandle, a leaf spring held between t e blocks and arranged to engage theratchet teeth, a U-bolt extending through the blocks and arranged tohold the spring and blocks in placein the handle member, the rotatinelements being provided with a rectangu ar central aperture, a pluralityof rectangular jaw members arranged to telescope within each other, eachof said jaw members bein provided with a pin and having a slot in theside opposite the pin, the said pins and slots being arranged to limitthe movement of the'jaw members with relation to each other, and meansto hold the cooperating elements in operative position.

In testimony whereof I afiix -my signature in presence of two witnesses.

CHARLES STARKS.
